4. Urban Conservation Programs
The urban conservation program is marked by its core of changing
customers and the mix of agencies and skill-levels involved in planning
and implementing urban projects. It is not unusual to find both public
NCSS cooperators,
and private soil consultants working at the request of
a community non-profit group such as a conservation district. The
concepts of social good and stewardship of the land blend with
nutritional concerns and recreational needs to intensify the variety of
landuses co-existing on an urban parcel. The risk levels for unsuitable
choices for land use mean higher economic cost in urban areas,
necessitating a more specific and risk-sensitive method of comparing
soils within a given site.
The soil survey manuscripts produced for traditional scales of soil
survey are undergoing changes in the direction of the needs for urban
surveys, such as updating the sample descriptions for interpreting soil
suitability for different uses (prewritten manuscript material),
adapting the three-rating system (slight, moderate, severe) to use fuzzy
logic in a continuous rating of likelihood of suitability from 0.0-1.0,
and addressing the need for new interpretations to fit modern types of
recreation. Traditional concerns such as the degree of soil
limitation, passive recreation, heavy foot traffic, vehicles, flooding,
and avoidance of boulders and dust remain and are joined by concerns
with more difficult research areas such as heavy metal toxicity and
contamination plumes.
Limitations to successful local programs in urban soils include
funding, experienced people, scientific knowledge, and customer input.
Six projects were started in 1996-97 to demonstrate the potential
of urban soils programs when funding was removed as a barrier. Funds
were obtained through the
USDA-NRCS-Community
and Rural Development Division (CARDD) and cooperative agreements were written for the
development of prototype urban soils products. The projects and
locations varied but shared common formats of futuristic planning,
contracts with external customers to help them lead by
example, and as prototypes
for USDA-NRCS agency
direction.
